While there are villagers I hate, these five criminals would have to be my worst ever:
Merengue is my number one most hated enemy of all time, she's the most notorious for loitering around in one of my New Leaf towns, she never wanted to move out. I tried SO HARD to get along with her after I got her randomly, even though I didn't really want her. It was the last straw when I saw that she kept hanging out with T-Bone, even though he's mine... :c
I hit her, pushed her, and reported her to Isabelle at the town hall for MONTHS!
She's boring, plain, and most certainly overhyped. I gave up trying to kick her out and I reset the town to get rid of her myself.
I also hate Diva, but not for the reason people hate her. She's not even ugly at all, it's because she's also banned from showing up in my towns ever again after also expressing an interest in T-Bone.
Chops physically gives me the creeps, his face is very ghastly looking...he is the ugliest villager ever in my eyes.
Kid Cat is a prideful jerk whose house killed a few of my regular fruit trees. They weren't perfect, but, still...
He started fights with Doc, and wouldn't move for 5 months, and gloated to my villagers about winning a contest. He once tried to move out, but then he changed his mind.
Big Top is the only other one I have beef with. He moved in front of my town hall in my secondary New Leaf town, and he had a conversation with Vic that left him upset, while Big Top cheered...jerk.
